Properties
disabled
Type: boolean
When disabled, the button is rendered as "dimmed" and prevents all user interactions (mouse and keyboard).
Since disabled buttons are not focusable and cannot react to hover
events by default, it can cause accessibility issues by making them
entirely invisible to assistive technologies, and prevents the use
of Tooltips to explain why the action is not available. This can be
addressed by enabling the feature flag accessibleDisabledButtons,
which makes disabled buttons focusable and hoverable, while still
preventing them from being triggered:
// Set before any button is attached to the DOM.
window.Vaadin.featureFlags.accessibleDisabledButtons = true
